Given the quality of the DAC unit in the Z-5500's your better off using analog with the Z-5500's if you have a modern soundcard. A digital conenction to that system will actually be a downgrade in sound quality in most cases.

The Edifier's are definatley nice, They have many nice systems. Unfortunatley, You may never see this system here in North America....

I have an optical cable (miniplug to toslink) on the way to my house (unless UPS lost it...) and I'll chime in on if there is any difference with optical vs. analog.

It doesn't surprise me that the Logitech DAC's are crap by no means is product classifed as audiophile material. For the average computer enthusiast like myself and by no means am I any expert in Audio products I have been pretty happy with them, every product has it limitations good and bad. In short if I had the $$$$ I'd have an amazing sound system with more qaulity built into the system than value as for now the Z5500 are a suitable subtitute for my budget.

Edit: You are right robscix after further exploration and a more technical review of the Z5500 they are indeed quite inferior to most modern day Soundcards. Clearly the Z5500 are due for an overall technically and personally I'd like to see at a minimum 2 way statilite speakers used in a new design.

Its a shame we might never see the Edifiers, than again if the right arrangements can be made you can always get what you want for a price.

@Eagle eye, I am not saying the Z-5500's are a total bad product not at all. They offer a great product for the price.
AS for the DAC, if your using a motherboard onboard then the Z-5500 DAC would give you a upgrade in sound. The newer modern cards have some high end DAC's
The Z-5500's have been around forever...would be nice to see Logitech revise the design and make a system that is viable for todays customers...
Susch as:
Two Way Satelites
10" Subwoofer
High Quality DAC
better frequency control over the sub.
Wooden boxes on Sats and subwoofer.
Possible class "T" amplifier stages
There is alot of other features I would like also but this would be a great starting point. For the sake of conversation, If you guys could have what you want on a "PC" speaker system, what would you want?

I'm not concerned with wattage, I just want quality sound from 30hz-20000khz, with main speakers capable of 60hz, but roll-off @ 80hz. I want sound played from the speakers to sound the same as live...which I basically have now...but I'm not using pc speakers, because none offer this.

As far as I am concerned, you can buy any HTIB for the same price as the z-5500, and get similar sound. How the hell can I get a full reciever, dvd player, etc, for the same cost, with the same sonic value?
